What is Lay Betting?
Lay betting is effectively "betting against" an outcome. When you lay a horse, team, or player, you are acting as the bookmaker—you win if the selection loses.
Key Terms:
- Liability: This is the amount you stand to lose if the selection wins. It is calculated as
Stake × (Odds - 1). - The Commission: Betting exchanges (like Betfair or Smarkets) charge a small percentage fee (usually 2% to 5%) on your net winnings.
- Hedged Lay: This calculator helps you determine the exact stake needed to "equalize" your profit across all outcomes, often used in Matched Betting.
Caution: Always ensure you have enough balance in your exchange account to cover the Liability, not just the stake.
